Hi,
There are two things that could mean, so here is both.
To change that "Mindblown: a blog about philosophy" line: in WordPress go to Appearance, then Editor, then Templates, then Blog Home. Click directly on the heading text, type whatever you want in its place, and press Save. If you would rather it were not there at all, click the block and delete it.
The bigger one, and I suspect this is what you are really asking: your front page is showing your list of blog posts instead of your restaurant. You already have a proper homepage written and published at concolon-restaurant.com/home, with your About Us, your locally sourced ingredients and your visit us section. It simply is not set as the front page.
To switch it: Settings, then Reading, then choose "A static page". Set Homepage to "Discover the Best Panama Restaurant for Local Cuisine". Make a blank page called Blog and set that as the Posts page. Save. Visitors then land on the restaurant, and your posts move to their own page.
If you would rather not poke around in settings, grab fifteen minutes here and I will walk you through the screens: https://cal.com/clearpost/15min

/wp-content/themes/twentytwentythree/ and is-block-theme in the body class. So the path is Appearance → Editor (the Site Editor), NOT the old Customizer. Giving them Customizer steps would have sent them somewhere that does not exist in this theme.<h1 class="alignwide wp-block-heading">Mindblown: a blog about philosophy.</h1> sitting inside <main> directly above the posts query loop. Their actual tagline in /wp-json/ is the real restaurant description, so telling them to edit Settings → General would not have touched it.home blog.status: publish, 210 words, opening "Panama restaurant you will love! Waiting for you", with About Us and a visit-us section. I checked before pointing them at it.
